Title: Process and plant for decreasing the pollutant content in the exhaust gas of an exhaust gas source
Inventor: HEILEMANN PAUL
IPC: B01D53/34
Filed: 1988-03-15
Abstract: Process for decreasing the pollutant content in the exhaust gas of an exhaust gas source, in particular in the flue gas of a furnace, by binding the pollutants to solid particles, these being delivered as a fine-grained, dry additive to the pollutant-laden flue gas in a mixing stage of a reaction section through which the flue gas flows, forming a suspension stream in the form of a fly dust cloud and the solids particles becoming enriched with pollutants in the contact with the flue gas during transport through the reaction section, preferably in a reaction stage provided therein, and at the end of the reaction section, after saturation with pollutants, being separated off from the flue gas in a separation stage, characterised in that the suspension stream is subjected in the reaction stage to a classification of the solids particles entrained therein according to the mass or weight of the individual solids particles and is separated into a fine dust fraction and into a coarse dust fraction and the fine dust fraction is discharged from the reaction stage in suspension with the flue gas stream as fly dust cloud and being introduced into the separation stage for secondary reaction and the solids-saturated fine dust is separated therein from the flue gas, and in that the coarse dust fraction is recirculated as partially-saturated material to the mixing stage and is delivered therein again to the pollutant-containing flue gas together with fresh additive. <IMAGE>

Title: Mechanical recoil-spring brake
Inventor: MENDEL HANS WOLFGANG
IPC: B60T1/00
Filed: 1988-03-22
Abstract: Mechanical recoil-spring brake for slowly turning gearboxes, drive units, motors and mechanical movement constructions. The mechanical recoil-spring brake can be classified as exceptionally favourable in terms of space and costs because of its simple constructional features (roll-spring and fixing point). Since the supplementary or exchangeable individual parts can consist of standards, a large field of application is cost-effectively encompassed by its universal introduction. The low stock-keeping and low service costs contingently incurred additionally have a positive effect because of the minimal size and quantity of the components.

Title: Method for disposing of coarse-grained rock material containing oil and/or grease
Inventor: KADELKA FRIEDRICH
IPC: B09C1/00
Filed: 1988-10-27
Abstract: The invention relates to a method for disposing of coarse-grained rock which contains oil and/or grease and is brought into an intimate mixture with fine-grain rock material in a directly or indirectly heated rotary furnace, a drying drum or a heating assembly, said fine-grain rock material having a large specific surface. In this case, a transfer of the oils and greases takes place to a great extent onto the fine-grain rock material. Subsequently, the fine-grain and coarse-grain rock materials are separated from one another again using screens. The cleaned coarse-grain material is reused and the contaminated fine-grain material may be subjected to aftertreatment prior to being processed.
Patent DE-3839597-A1 (DE)
Inventor: HAENEL MICHAEL DIPL ING
IPC: F16P3/10
Filed: 1988-11-24
Abstract: A cabinet (1) comprises access openings, which are displaceable, for example, with the aid of sliding roller doors (3, 5), for access to the interior of the cabinet (1). In the interior of the cabinet (1) there are electric motor driven parts, for example for setting down index card boxes (9) which are moved past the access opening (7) in a paternoster-type movement. It is guaranteed by a safety device that the movement only takes place with the coverings (3, 5) closed. The safety device provides for the coverings (3, 5) each to be fitted with an electric circuit section (21a, 21b) which are removed from a safety loop (17, 19) when the coverings (3, 5) are opened. By this means, a stoppage of the moved parts (9) is inevitably brought about. The electric circuit sections (21a, 21b) have contact parts (23a, 23b) which can be brought into engagement in corresponding contact elements (15a, 15b) which are attached to the housing (1). The cabinet (1) offers the advantage that it is largely protected against manipulations on the safety device since the removal of a complete electric circuit section (21a, 21b) cannot be carried out using simple measures, such as jamming a contact by means of a match, paperclip or the like. <IMAGE>

Title: Window, in particular for sloping roof surfaces
Inventor: SCHWEIZER HARALD
IPC: E06B7/20
Filed: 1988-12-13
Abstract: The invention relates to a window (1), in particular for sloping roof surfaces, having a window sash (3) or similar window element, which, for opening the window (1), is guided such that it can be laterally displaced in a sliding guide, and having at least one seal (5) which is arranged, in the closed position, between window sash (3) and built-in frame (2). In order, by means of the seal (5), also to be able to close off a large-dimension window (1) in a sealed manner with a low degree of outlay, according to the invention the seal (5), in the closed position of the window (1), can move relative to the built-in frame (2) connected to it and can be pressed against the window sash (3) or the like and can be displaced away therefrom. Expediently, the sash frame (7) is guided such that it can be displaced laterally approximately parallel to the glass plane of the window sash (3) or the like located in the closed position and is retained such that it cannot move perpendicularly to said plane. With corresponding dimensioning of the window opening (4) and of the window (1), roof balconies or loggias can thus also be subsequently built into old buildings, which balconies or loggias, for example as roof recesses which restrict the living area, have, as a result of the sealing problems and water-discharge problems, been possible up until now only with difficulty and a high degree of outlay (see Figure 1). <IMAGE>
Patent DE-3900526-A1 (DE)
Title: Ultra-thin diaphragm having a supporting edge
Inventor: LOECHEL BERND DR
IPC: G03F1/22
Filed: 1989-01-10
Abstract: In known ultra-thin diaphragms, supporting edge and diaphragm form a discontinuous transition, as a result of which high notch stresses occur, which often lead to rupture of the diaphragm. The novel diaphragm is connected to the supporting edge via a stabilising transition region, which rises smoothly on the diaphragm side and opens into the supporting edge at a steep angle. By this means the diaphragm is exposed to lower notch stresses and the danger of rupture is considerably reduced. With the method specified, such diaphragms are manufactured with the aid of the methods of planar technology and microstructure technology. With the aid of the device described, the manufacturing process can be simply configured. By means of the higher load-bearing capacity, the diaphragm is suitable for use in X-ray lithography, in optical lithography, for electron or ion projection and as an acoustic transducer or pressure sensor. For use as a mask substrate in chip manufacture, the configuration as a rectangular membrane is particularly suitable.

Title: Method for local traffic data acquisition and evaluation
Inventor: STAMMLER WALTER DR ING
IPC: G01S7/41
Filed: 1989-01-28
Abstract: The invention relates to a method for local traffic data acquisition and evaluation on the basis of real-time evaluation of Doppler echoes on a digital basis, the frequency spectrum of the Doppler echoes being formed initially, the frequency having the maximum amplitude in this spectrum subsequently being determined, and this frequency being used to determine the speed of the recorded vehicle, and the vehicle speed and the Doppler echo signal duration being used to determine the vehicle length. The frequency spectrum of the Doppler echo is formed either by direct spectral transformation or by autocorrelation or relay correlation with spectral transformation associated therewith, the spectral transformation being carried out using a non-linear estimation method which is preferably based on an AR model or ARMA model.
